摘要/Abstract

摘要： 鄂尔多斯盆地西南部沉积了一套巨厚的以王全口组为代表的中元古代碳酸盐岩层系。为预测其油气勘探前景，文章采用主、微量元素地球化学方法，探讨王全口组的岩石特征、沉积环境、构造背景及其内硅质岩的成因。结果表明，王全口组以白云岩、硅质白云岩和硅质岩为主，并含有少量石英砂岩。其中，硅质岩和硅质白云岩内硅质为生物化学成因，且几乎未遭受到陆源碎屑物质影响。V/Cr，Ni/Co，V/（V+Ni）和Ce/La氧化还原环境判别图显示，王全口组整体形成于富氧或贫氧过渡状态下的浅水沉积环境。古水温数据与Sr/Cu比值反映的结果一致，即王全口组沉积期区域古水温相对最高，应为干燥炎热的气候背景。Sr/Ba，CaO/（CaO+MgO）海陆环境判别图、Y异常和（La/Nd）_pass值表明，除砂岩样品外，王全口组碳酸盐岩整体形成于海相咸水环境或次咸水过渡沉积环境。综合La-Th-Sc，Th-Co-Zr/10和100Eu/∑REE-LREE/HREE图解，王全口组碳酸盐岩样品具有大陆岛弧,活动陆缘和陆壳-浅海沉积体系特征,且陇县固关、炭山和盆缘桌子山地区样品同样具有高稀土含量特征，进一步表明王全口期研究区应具有大陆岛弧弧后坳陷构造背景特征。总而言之，在陆缘弧后坳陷背景和干热气候、弱氧化的浅水海陆过渡环境下，区域发育了生物化学成因的碳酸盐岩与硅质岩。

Abstract: A very thick Middle Proterozoic carbonate strata represented by the Wangquankou Formation is distributed in the southwestern Ordos basin.In order to forecast its petroleum exploration prospects, major and trace elements were measured on samples to reveal the rock characteristics, sedimentary environment, tectonic settings and origin of siliceous rocks of the Wangquankou Formation.The Wangquankou Formation mainly consists of dolomites, siliceous dolomites and silicalites, with minor quartz sandstones.Geochemical features of siliceous materials in silicalites and siliceous dolomites clearly show a biochemical origin, with almost no influences from epicontinental clastic input.Discrimination diagrams of redox environment, such as V/Cr, Ni/Co, V/(V+Ni) and Ce/La, indicate that the Wangquankou Formation was deposited in aerobic or transitional dysaerobic shallow water.Paleo-temperature data, in good agreement with Sr/Cu values, suggest that regional temperatures were highest during deposition of the Wangquankou Formation, further indicating an arid and scorching climate background.Sr/Ba and CaO/(CaO+MgO) environment discriminant graphs, Y abnormity and (La/Nd)_pass ratio show that the carbonate rocks formed in marine saltwater or transitional semi-saltwater environment.A comprehensive analysis of various diagrams, such as La-Th-Sc，Th-Co-Zr/10 and 100Eu/∑REE- LREE/HREE graphs, indicates that carbonate samples from the Wangquankou Formation carry information of active continental margin, continental island arc and middle continent-shallow water sedimentary system.Samples from regions of Long Country Guguan, Tanshan, and Zhuozishan located at the basin margin are all characterized by high REEs, indicating a tectonic background of continental back-arc depression during the Wangquankou Stage.In conclusion, siliceous rocks and carbonate rocks of biochemical origin in this region were deposited in mild-oxidizing, marine-continental transition environment, with the backgrounds of desiccation and torridness with the tectonic settings of epicontinental back-arc depression.
